What Is It For?

BeanShell is a small, embeddable Java source interpreter with object scripting language features, written in Java. BeanShell dynamically executes standard Java syntax. So, using BeanShell Plugin, you can type in valid Java codes in plugin configuration, and the statements will be executed when the plugin is triggered. No compilation cycle is needed.

Configurations

1. Script

The script can be composed of:

  • Java syntax supported by the version of JDK used
  • Usage of the following libraries:
    • Libraries available in JDK
    • org.joget.workflow.model.*
    • org.joget.workflow.util.*
    • JavaBeans Activation Framework 1.1
    • Commons Email 1.1
    • JavaMail 1.4
    • MySQL JDBC Driver 3.1.14
    • Oracle JDBC Driver 10.2.0.2
    • Microsoft SQL Server JDBC Driver 1.0
  • Usage of [Hash Variables|../../../../../../../../../display/KBv2/Hash+Variables]

    Example

Set value to a workflow variableimport org.joget.workflow.model.service.*;

WorkflowManager wm = (WorkflowManager) pluginManager.getBean("workflowManager");

wm.activityVariable(workflowAssignment.getActivityId(), "variableId", "variableValue");

Execute SQL statement through JDBCimport java.sql.*;

Connection con = null;

try {

Class.forName("com.mysql.jdbc.Driver").newInstance();

con = DriverManager.getConnection("jdbc:mysql://localhost/wflowdb?useUnicode=true&characterEncoding=UTF-8", "root", "root");

if(!con.isClosed())

Unknown macro: { System.out.println("Successfully connected to MySQL server using TCP/IP..."); PreparedStatement stmt = con.createStatement(); stmt.executeUpdate("UPDATE formdata_simpleflow set c_status='#assignment.activityId#' WHERE processId='#assignment.processId#'"); }

} catch(Exception e)

Unknown macro: { System.err.println("Exception}

finally {

try

Unknown macro: { if(con != null) con.close(); }

catch(SQLException e) {}

}

Participant Type Plugin

A participant type plugin should return a collection of usernames. In the participant plugin there are two context variables available for the script to use  :

  • pluginManager
  • workflowActivity

A Beanshell Participant Type Plugin returning one Participantimport java.util.ArrayList;

a = new ArrayList();

a.add("jack"); // one username

return a;

Activity Tool Type Plugin

Activity tool type plugin is a plugin that will be executed when workflow reached a System Tool activity. System Tool activities must be placed in the workflow diagram, and then the Beanshell plugin configured in the Process's Activity Mapping for this to work.  In this plugin there are two context variables available for the script to use :

  • pluginManager
  • workflowAssignment

A Beanshell Activity Tool type plugin that sets a form dataimport java.util.ArrayList;

import java.util.logging.Logger;
import org.joget.plugin.base.PluginManager;
import java.util.logging.FileHandler;
import org.joget.workflow.model.service.WorkflowManager;
import org.joget.form.model.service.FormManager;
import org.joget.form.model.Form;

FormManager formManager = (FormManager) pluginManager.getBean("formManager");
processId = workflowAssignment.getProcessId();
Form form = formManager.loadDynamicFormByProcessId("T01", processId); // in this example, form's table is T01

formData = form.getCustomProperties();
formData.put("c_columnname","new value"); // the form data field to be set is columnname
form.setCustomProperties(formData);
formManager.saveForm(form);
